Pop-rocker Liz Phair [ tickets ] has settled on a title and release date for her forthcoming album, and has added a three-night Chicago engagement to her current nine-city acoustic tour.

"Somebody's Miracle," Phair's fifth studio album, will hit stores Oct. 4. The set was jointly produced by John Algaia (Dave Matthews Band, John Mayer) and John Shanks (Sheryl Crow, Chris Isaak), and features 14 new songs--11 written by Phair herself, with the remaining three co-authored by producer Shanks.

The former lo-fi rocker--who became a critical darling upon the release of her 1999 debut, "Exile in Guyville"--enlisted slick producers and several guest musicians for the 2003 album, including Mike Elizondo (Dr. Dre's bassist and co-writer/producer of 50 Cent's hit "In Da Club"), drummer Matt Chamberlain (Tori Amos, The Wallflowers), bassist Wendy Melvoin (Prince and the Revolution) and Pete Yorn.

"People get very uptight about staying in a certain genre or not breaking out of your expected style," Phair said in a press release. "If I like indie-rock, I can't like pop. Or if I'm a pop person, I have no credibility in rock. But for me, I just decided to go farther and take my aesthetic stand stronger. I like demos and I like high pop production and I like straight American rock and I like jazzy, minor trippy chords. I like it all."

Phair was recently selected, along with Joss Stone and Keith Urban, to appear in Gap's two-month long fall television and print advertisement campaign. She previously appeared in a series of Gap ads that ran during the 2001 holiday season.
